OpenAI o-series reasoning models: pricing bands, key models, and next actions

Built for complex reasoning, tool use, and agent workflows, with intent close to real technical decisions. This page is not here to dump names. It compresses the OpenAI route into a family-level entry, then routes people toward latest releases, pricing, alternatives, and direct key checks.

OpenAI o-series reasoning models

Built for complex reasoning, tool use, and agent workflows, with intent close to real technical decisions.

Family members

Family pages work because they cluster the representative models from one route before deeper decisions begin.

Provider route

OpenAI

This page does not replace the provider page. It translates provider supply into a more searchable family-level entry.

Context band

200K

The context spread across one family often determines which workflows it can really carry inside the global model route.

Input price band

$1.1 - $10

The price band across one family is often closer to a real sourcing decision than any single model.

Route judgment

OpenAI o-series reasoning models should not behave like a loose list of names. It should help people judge the real decision route inside OpenAI before they move deeper.

Built for complex reasoning, tool use, and agent workflows, with intent close to real technical decisions. The current family input price band is roughly $1.1 - $10, with a context band around 200K, which makes it strong enough to stand as its own high-intent entry page.

The main value of this page is to place the relevant models from one family side by side so users do not keep bouncing through directory pages without making a real judgment.

Next actions

Once the family is clear, keep moving forward

Open the OpenAI reasoning family provider profile

The family page explains the route. The provider profile explains protocol, base URL, and the broader supply position.

Once someone compares a family seriously, the next step often returns to pricing layers and supply structure.

A natural next step after the family page is to place the route inside a real A-vs-B comparison.
